It’s no secret construction is one of the most dangerous industries. In 2015, the private construction industry incurred approximately 200,000 non-fatal injuries and 937 fatal injuries according to the U.S. Department of Labor’s Bureau of Labor Statistics.

With such dire statistics, keeping workers safe is a challenge. But safety-related tech gets better each year. Here are just three innovative technologies that may help reduce the risk of accidents.

Drones

Drones can go places that can be risky to humans. In 2016 the Kansas Department of Transportation began using them for bridge and tower inspections.

“Our Aviation and Bridge inspection teams are doing great work in testing drones to enhance the safety of KDOT workers and improve cost efficiencies,” said acting transportation secretary Richard Carlson in a press release. “We believe UAS may reduce the need to place our engineers in potentially dangerous situations and we intend to pursue every opportunity that makes them more efficient.”

The just-completed Sacramento Kings Arena was built using a drone system called the Flying Superintendent, which, in conjunction with 4D BIM, allowed on-site and off-site personnel to analyze work in progress. Besides helping with quality control, the system improved safety by providing “a clear and immediate understanding of potential hazards,” according to the team at the University of Illinois that developed the system.

GPS

GPS lets you track the location of your construction equipment and can even let you know when the engine is turned on — potentially helping you make sure employees such as crane operators are complying with certain labor laws. But other uses are emerging.

Redpoint Positioning is developing an innovative safety vest using GPS-like real-time location services (RTLS). When a worker enters a hazardous zone, defined in BIM software, the vest flashes and gives out an audible warning. It also sends a signal to the appropriate manager and records the incident in a cloud database. The vests could also be used to monitor workers relative to certain pieces of equipment.

According to Antti Korhonen, president and CEO of Redpoint Positioning, the vest is available in small quantities for testing and piloting and will become commercially available in the second half of 2017. The Redpoint B3 Workforce Safety Badge, which alerts the worker with a strobe light and beeper integrated in the badge, is available now.

One company, DAQRI, has developed a helmet with AR functionlity built in. Last year DAQRI partnered with Mortenson Construction to test the Smart Helmet, which is equipped with a visor that can display all manner of information in 3D overlays — think schematics, step-by-step work instructions, even safety alerts (there’s too much pressure in that pipe!). The helmet allows for real-time communication with remote personnel. The thermal vision capability can even warn of heat dangers.
